If you ever get rice/pasta stuck on the bottom of a pan, you can use a dryer sheet to scrub it off!
I had burned some food on an iron pan. I filled the pan up half way with water and added soap and a dryer sheet. After two hours the pan was 100% clean—all I had to do was rinse it out.
According to this video, you might have to soak the pan with water, dish soap, and a dryer sheet. Then you can use the dryer sheet to wipe the gunk right out. And be sure to thoroughly wash your pan with *just* dish soap after, to remove any dryer sheet residue.
